Changing Manual Transaxle Gear Oil

The process in this video applies to all import FWD/AWD cars. Honda, Mitsu, Nissan, don’t matta… Oils and torque ratings specific to the AWD and FWD turbo Eclipse are outlined in addition to tools to do this job. This is considered elementary, yet most people have a service center do this for them. Like many of those people eventually learn, it’s best to do this yourself. If you’ve ever wondered how to do this, here it is.

    ;) you’re good man! Yes, the thing at 3:45 is one of the best [tiny] investments a DIY’er can make. If you use a funnel, you’re going to have a bad time.

    In my Trans & Clutch AWD Fluids video, I use a gear oil whose bottle has that kind of tube thing you describe built right into the bottle. Not only is it GREAT oil for an AWD DSM, it’s thoughtfully packaged by its manufacturer. Don’t use it just because of the bottle, unless you know it’s the right oil for your transmission.

    Point taken. Im gonna have to find out if the containers of oil have a thread that i can attach a tube type thing to, like the ones that can be bought in motor factor stores. Dont fancy doing it with a funnel

  3. Jafromobile says:

    You’re correct; however, you don’t need to know how much oil it takes. The correct amount is based on a fill level. The point I demonstrated leveling and lowering the car was to ensure the level was correct. You fill it until it runs out the fill hole. Only then will it be at the proper level on the axle seals.

    For people like me who have changed gear sets, and added bigger, beefier & additional parts, a static amount of oil won’t work because they’ll displace the oil raising that level.

    U said you werent too clear on how much oil it’d take. Bad idea tho,as 1st things to go will be ur g box oil seals

    love the sound effect…

    Thanks, I watched several films tried to figure out where is the right bolt or plug, finally, I saw the plug position very clear in your video,

    badass vid I dig

  8. RSXKane says:

    i finally found the right bolts but it looks nothing like yours the drain plug is on the back side of the transmission but it didnt really fix my issue it helped a little with the new syncromesh oil but some times its still tough as hell to get in to first
    could this be a broken mount? i think perhaps the one on the back side of the motor is broken and maybe everything is miss alined by a small amount
    thx for the help before and any help u can give me

  9. Jafromobile says:

    The fill bolt is on the front of the transmission (if you’re standing at the front of the car). It’s oriented about 8″ up from where the fill bolt is, and should be directly to the left of the shift fork.

    The bolts you don’t want to risk taking loose are the 3 14mm bolts lined up with each other. There are spring loaded ball bearings behind them. The fill bolt is by itself.

  10. RSXKane says:

    Its the fill plug I can’t find I have to assume its on the side but the one I can find isn’t even close to 17mm

  11. Jafromobile says:

    The drain bolt on manual transmission cars should be at the lowest point of the transmission case when the car is level. It’s a huge bolt. 24mm or 15/16″ I think. I have another video about AWD fluids that covers this in less detail, but in 1080 HD. It’s in my Trans & Clutch series.

  12. RSXKane says:

    I’m trying to do a fluid swap but I can’t see the fill bolt I’ve lookes jacked the car up and looked and there is 1 bolt but its really small and pretty low on the transmission the car is a 97 gst

  13. chris2756832 says:

    I think my car doesnt have much gear oil left, i have the same car as you except its a GST, it won’t go into gear anymore meaning it wont move, i had a “mechanic” tell me it was the slave cylinder, which i replaced already and it still doesnt work, I’m gonna try to see if it has oil or not, i know metal shit is gonna come out because when first learning to drive standard i grinded the bears a bit too much

  14. Jafromobile says:

    Yes, absolutely. Or it could be low. BUT… If you change the gear oil with the recommended fluid and it still shifts like a Choda Boy, that indicates the syncro’s are worn. Changing to a different fluid might resolve the issue.

    A small amount of friction is actually necessary in a manual transmission. When you shift, it’s what lets the syncros do their jobs to change the speeds of the gearshafts so you can easily shift. If the gear oil is too slippery, they might not work.

    I have an 87 nissan nivara 4wd manual. Changing gears up is fine but changing down in2 2nd and 1st is really hard, i really have to force it in.
    Could this be because my i need to change the tranny oil?

  16. gerjaison says:

    Looks efficiently done! 

  17. MrDumess says:

    good advice man im going to do this on my 1999 eclipse only feed back in my opinion is clean ur working area u dont want your parts with dirt and shit

  18. CheapAntivirus says:

    Hi I would like to ask a question i got new car but after few almost a year of driving the reverse gear start jerking…Whenever reverse every morning its just jerking quite hard.

    Does that got something to do with gear oil not enough?

  19. TheDSMsucka says:

    Thanks man. easy to follow and understand.

  20. jkelly6620 says:

    Thanks. Great advice.

  21. Jafromobile says:

    Actually, I don’t know? TRE always installs them, and I’ve been through 3 of their transmissions… so somewhere along the line it happened. I don’t know if the stock plug is magnetic? TRE sells them as replacement parts. Not sure if it’s an OEM part, or if he modifies them, but you can order it by itself.

  22. StickGuy0000000001 says:

    do they come stock with the magnetic cap or is that something you put in yourself?

  23. omartron says:

    MONSTER energy :D

  24. godrilla says:

    I have a 1997 3000gt SOHC 5 speed. What happens if you don’t change the gear oil? I’m going to replace my soon, but I think the effects of not changing the gear oil are already happening, such as hard and rough shifting..

  25. Jafromobile says:

    I’m positive that it is possible to remove any car’s drain/fill plugs. Perhaps you’ve run into an aluminum oil pan? If so, the process is still the same, but you have to be careful not to strip the bolt or the pan when installing and removing the plugs. Those pans are expensive to replace. EricTheCarGuy covered this sort of thing. The way you asked your question sounds like you’ve found a bolt you don’t have a tool for, like a 10-point socket or a Torx? You’d just need the tool.
